Summary
🤩
Rockstar🎓
Top SchoolBhavana Kilambi is a Senior Software Engineer based in Cambridge with four years focused on low-level performance engineering and JVM optimizations at Arm. She contributes to the high-profile openjdk/jdk project, improving HotSpot C2 compiler code paths and enabling Arm-specific CPU optimizations like Neoverse N1 and auto-vectorized integer operations. Her background in performance analysis at IBM—using hardware counters and SPEC benchmarks on POWER—gives her a rare combination of compiler internals knowledge and hardware-aware tuning. Trained in electrical engineering and information technology, she also holds advanced coursework in quantum machine learning, reflecting a curiosity for emerging computation paradigms. Colleagues rely on her for measurable performance gains across architectures and for turning microarchitecture insights into practical compiler changes.
